Description

Technical Field

[0001] The present invention relates to the technical field of plant processing and milling, and specifically to a high-efficiency milling device for plant active ingredients. Background Art

[0002] Plant active ingredients refer to chemical components in plants that have specific physiological activities and can have beneficial or regulatory effects on health or metabolism. These components usually participate in the defense, growth, or reproduction of plants and have medicinal, nutritional, or functional value for humans. For some dried parts such as the roots, stems, leaves, flowers, fruits, and seeds of plants, during the processing, they need to be mechanically milled and crushed. Therefore, corresponding milling devices are required.

[0003] However, after long-term use of existing milling devices, it is found that they still have the following defects: (1) Single-tank (box) type milling is adopted, that is, the single-time milling treatment capacity is limited; (2) The adjustment ability during milling is insufficient, that is, it is impossible to gradually mill and crush plant raw materials, and at the same time, the transfer of raw materials lacks flexibility; (3) The linkage between the involved power systems is insufficient, that is, it leads to low conversion rate and utilization rate of kinetic energy, resulting in waste of resources and increase in costs.

[0004] Therefore, in view of the above problems, the present technical solution proposes a high-efficiency milling device for plant active ingredients. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-efficiency milling device for plant active ingredients to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A high-efficiency milling device for plant active ingredients includes a plurality of milling tanks arranged at equal intervals in a ring shape. A conical milling disk is rotatably arranged on the lower side of the middle part inside the milling tank. A milling ring is swingably and rotatably arranged on one side of the inclined surface of the conical milling disk. The plant active raw materials entering the inside of the milling tank spread downward along the inclined surface from the top of the conical milling disk. At this time, the conical milling disk and the milling ring rotate to mill it. At the same time, multiple rows of elastic dividing rings are arranged at equal intervals along the length direction of the inclined surface of the conical milling disk. The elastic dividing rings are used to gradually mill and filter the plant active raw materials on the inclined surface of the conical milling disk. At the same time, when the elastic dividing rings are squeezed by the milling ring, they automatically contract, and when they lose the extrusion of the milling ring, they reset to block and filter the falling plant active raw materials, so as to realize the self-mobile and gradually milling processing of the plant active raw materials; The bottom of the frustum-shaped grinding disc is connected by a connecting shaft to a swing-type rotating assembly arranged outside the bottom of the grinding tank. The swing-type rotating assembly is used to drive the frustum-shaped grinding disc to rotate. At the same time, the swing-type rotating assembly is commonly connected to a set of main power mechanisms towards the middle position of all grinding tanks. The main power mechanism includes a main driving servo motor and a multi-axis output assembly connected to the top output end of the main driving servo motor. Each output end of the multi-axis output assembly is correspondingly swing-connected to a set of swing-type rotating assemblies. In this way, by using the rotational kinetic energy of the main driving servo motor, under the transmission and diffusion of the multi-axis output assembly, it is output in multiple directions, thereby driving the swing-type rotating assembly to drive the frustum-shaped grinding disc to rotate, realizing the full conversion and utilization of kinetic energy; At the same time, the main power mechanism also includes a main shaft installed at the top end of the main driving servo motor. The end of the main shaft is rotationally connected to an adjustable rotating assembly through a transmission belt in the direction towards each grinding tank. The output end of the adjustable rotating assembly is connected to the grinding ring, and is used to drive the grinding ring to rotate and adjust the position of its contact with the inclined surface of the frustum-shaped grinding disc, thereby realizing the step-by-step filtering grinding of the plant active raw materials on the inclined surface of the frustum-shaped grinding disc; The adjustable rotating assembly includes a power transmission unit rotationally connected to the transmission belt and an angle adjustment unit. The power transmission unit is used to transmit the rotational kinetic energy in the main shaft to the grinding ring to drive it to rotate. The angle adjustment unit is used to adjust the contact angle between the grinding ring and the inclined line of the frustum-shaped grinding disc, that is, to control the grinding process; That is, through the cooperation between the above-mentioned mechanisms, components, and units, the device can realize the simultaneous grinding treatment of a large number of different types of plant active raw materials, and fully improve the conversion rate and utilization rate of kinetic energy. At the same time, it adopts self-mobile step-by-step grinding and filtering, fully improving the processing accuracy and automation degree.

[0007] Compared with the prior art, the beneficial effects of the present invention are: realizing synchronous processing of batch raw materials through the annularly distributed grinding tanks, and the processing capacity is increased by more than 3 times; Realizing fine grading grinding of raw materials through the gradually decreasing filter holes of the elastic dividing ring and combining with the angle adjustment of the grinding ring; Distributing the kinetic energy of a single motor to multiple directions through the multi-axis output assembly, and the energy conversion rate ≥ 85%; Precisely controlling the grinding pressure and contact angle through the electric telescopic rod and the servo motor to adapt to raw materials of different hardnesses.

[0024] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0025] Please refer to Figures 1-7 、 Figure 11, a high-efficiency grinding device for plant active ingredients, including multiple grinding tanks 10 arranged at equal intervals in a ring shape. A conical grinding disc 12 is rotatably arranged at the lower side of the middle part inside the grinding tank 10. A grinding ring 33 is swingably and rotatably arranged on one side of the inclined surface of the conical grinding disc 12. The plant active raw materials entering the inside of the grinding tank 10 diffuse downward along the inclined surface from the top of the conical grinding disc 12. At this time, the conical grinding disc 12 and the grinding ring 33 rotate to grind it. At the same time, multiple rows of elastic dividing rings 13 are arranged at equal intervals along the length direction of the inclined surface of the conical grinding disc 12. The elastic dividing rings 13 are used to gradually grind and filter the plant active raw materials on the inclined surface of the conical grinding disc 12. At the same time, when the elastic dividing rings 13 are squeezed by the grinding ring 33, they automatically contract, and when the extrusion of the grinding ring 33 is lost, they reset to block and filter the falling plant active raw materials, so as to realize the self-mobile and gradual grinding process of the plant active raw materials; The bottom of the conical grinding disc 12 is connected by a connecting shaft to a swing-type rotating assembly arranged outside the bottom of the grinding tank 10. The swing-type rotating assembly is used to drive the conical grinding disc 12 to rotate. At the same time, a main power mechanism is commonly connected to the middle positions of all the grinding tanks 10 by the swing-type rotating assembly. The main power mechanism includes a main driving servo motor 17 and a multi-axis output assembly connected to the top output end of the main driving servo motor 17. Each output end of the multi-axis output assembly is correspondingly swing-connected to a swing-type rotating assembly. In this way, by using the rotational kinetic energy of the main driving servo motor 17, under the transmission and diffusion of the multi-axis output assembly, it is output in multiple directions, so as to drive the swing-type rotating assembly to drive the conical grinding disc 12 to rotate, realizing the full conversion and utilization of kinetic energy; At the same time, the main power mechanism also includes a main shaft 26 installed at the top end of the main driving servo motor 17. The end of the main shaft 26 is rotationally connected to an adjustable rotating assembly through a transmission belt 39 in the direction of each grinding tank 10. The output end of the adjustable rotating assembly is connected to the grinding ring 33, and is used to drive the grinding ring 33 to rotate and adjust the position in contact with the inclined surface of the conical grinding disc 12, thereby realizing the step-by-step filtering grinding of the plant active raw materials on the inclined surface of the conical grinding disc 12; The adjustable rotating assembly includes a power transmission unit and an angle adjustment unit rotationally connected to the transmission belt 39. The power transmission unit is used to transmit the rotational kinetic energy in the main shaft 26 to the grinding ring 33 to drive it to rotate. The angle adjustment unit is used to adjust the contact angle between the grinding ring 33 and the inclined line of the conical grinding disc 12, that is, to control the grinding process; That is, through the cooperation between the above-mentioned mechanisms, components, and units, the device can realize the simultaneous grinding process of a large number of different types of plant active raw materials, fully improve the conversion rate and utilization rate of kinetic energy, and at the same time adopt self-mobile and step-by-step grinding and filtering, fully improving the processing accuracy and automation degree.

[0026] In an embodiment of the present invention, a plant raw material inlet 11 is provided at the top of the grinding tank 10 for inputting plant active raw materials to be ground. At the bottom inside the grinding tank 10, a storage and transfer bin 16 is provided for collecting, storing, and subsequent outputting of the ground plant active raw materials; The bottom end of the plant raw material inlet 11 is connected to a funnel-shaped feeding channel, and the bottom end of the feeding channel extends to directly above the frustum-shaped grinding disk 12 and is spaced apart, ensuring that the plant active raw materials output from the feeding channel can diffuse along the top of the frustum-shaped grinding disk 12 towards the surrounding of its inclined surface; The bottom of the frustum-shaped grinding disk 12 is rotatably arranged in contact with the middle inside the storage and transfer bin 16, and a circle of screening slots 15 is provided at the top of the storage and transfer bin 16 around the bottom of the frustum-shaped grinding disk 12. The plant active raw materials ground along the inclined surface of the frustum-shaped grinding disk 12 slide into the screening slots 15, and then are screened through the screening slots 15 and transferred to the inside of the storage and transfer bin 16 for storage and subsequent output.

[0027] Refer to Figures 11-12 , a plurality of filter holes 14 parallel to the inclined surface of the frustum-shaped grinding disk 12 are evenly provided on the surface of the elastic dividing ring 13, and the diameters of the filter holes 14 on the elastic dividing ring 13 distributed from high to low along the inclined surface of the frustum-shaped grinding disk 12 decrease in sequence, thereby performing step-by-step grinding and filtering on the sliding plant active raw materials; A circle of buffer plates 48 is evenly installed at the bottom of the elastic dividing ring 13. The buffer plates 48 are vertically distributed, and a limiting ring 49 for preventing detachment from the inside of the frustum-shaped grinding disk 12 is installed at the bottom end of the buffer plates 48. A plurality of buffer springs 50 are evenly connected to the inner end of the limiting ring 49. When the buffer springs 50 are in a free state, the elastic dividing ring 13 is controlled to rise to the highest position. At the same time, the elastic dividing ring 13 is made of an elastic material. When subjected to the extrusion force of the grinding ring 33, it will deform synchronously by itself. When the extrusion force of the grinding ring 33 is lost, it will automatically recover synchronously. Then, combined with the elastic expansion and contraction of the bottom buffer plates 48, the limiting ring 49, and the buffer springs 50, it is avoided to affect the sliding of the grinding ring 33 along the inclined surface of the frustum-shaped grinding disk 12; Specifically, a sealing layer is provided on the surface of the buffer plate 48 in telescopic contact with the inclined surface of the frustum-shaped grinding disk 12 for preventing the plant active raw materials on the inclined surface of the frustum-shaped grinding disk 12 from falling into the telescopic gap; Among them, for the material selection of the elastic dividing ring 13, generally food-grade silicone rubber, polyurethane, or ethylene propylene diene monomer rubber, etc. can be used. The above materials can all be in contact with plant active ingredients and will not affect them.

[0028] In an example of the present invention, in this technical solution, pulleys are provided on structures such as shafts and rods rotationally connected to the transmission belt 39 for transmission connection with the transmission belt 39, that is, to ensure the stability of the connection; As a preferred embodiment of the present invention, refer toFigure 2 , Figures 4-6 , the multi-axis output assembly includes a power base ring 18 disposed directly above the main drive servo motor 17. Four groups of radially distributed piston cylinders 20 are evenly installed on the power base ring 18. A piston block 21 is slidably connected inside each piston cylinder 20. The end of the piston block 21 facing the outside of the piston cylinder 20 is rotatably connected to a swing type rotating assembly. The inner end of the piston block 21 is rotatably connected to a group of connecting circular blocks 23 through a rotating shaft 24. A group of swing power blocks 19 are arranged at the center of the power base ring 18 among the four groups of connecting circular blocks 23. The center of the swing power block 19 is fixedly connected to the output end of the main drive servo motor 17. That is, under the operation of the main drive servo motor 17, the swing power block 19 is driven to rotate. The swing power block 19 is set in a waist-like structure with the middle parts on both sides recessed inward, thus forming a shape with both ends protruding outward and both sides recessed inward, and the protruding and recessed parts are arc-connected. The outside of the swing power block 19 is in a distribution state of being in contact with the four groups of connecting circular blocks 23 at all times. Four groups of swing rods 25 are sleeved and connected among the four groups of connecting circular blocks 23. The four groups of swing rods 25 are distributed along the connection of the four groups of connecting circular blocks 23 and are evenly distributed on both sides of the swing rods 25. Among them, two groups of swing rods 25 on the same side are arranged in parallel. That is, when the swing power block 19 rotates, by using the structural trajectory of its protrusions and recessions, the connecting circular blocks 23 in contact with it are pushed to perform cyclic telescopic movement, thereby realizing the conversion of the rotational kinetic energy of the main drive servo motor 17 into four groups of linear telescopic operation transmissions.

[0029] As a preferred embodiment of the present invention, referring to Figure 7 , Figure 9 , the swing type rotating assembly includes a connecting block 22 installed on one side of the end face of the piston block 21. The connecting block 22 is rotatably connected outward with a swing connecting rod 27. An opening is provided on the side wall of the corresponding piston cylinder 20 of the swing connecting rod 27 to provide sufficient space for the swing of the swing connecting rod 27. The end of the swing connecting rod 27 is connected with a group of internal gears 28. The end of the swing connecting rod 27 is connected to the side edge position of the side of the internal gear 28. A group of external tooth rings 29 are meshed outside the internal gear 28. At the same time, a group of L-shaped swing connecting rods 30 are connected to the center of the side of the internal gear 28 opposite to the swing connecting rod 27. A rotating shaft is sleeved at the end of the L-shaped swing connecting rod 30. The top of the rotating shaft extends movably into the grinding tank 10 and is fixedly connected to the middle of the inner bottom of the frustum-shaped grinding disc 12. A connecting sleeve is fixedly installed on the rotating shaft facing the external tooth ring 29. The outer wall of the connecting sleeve is fixedly connected to the side wall of the external tooth ring 29 through a plurality of evenly distributed L-shaped fixing rods 31. That is, when the piston block 21 expands and contracts inside the piston cylinder 20, the swing connecting rod 27 is driven to swing, then the internal gear 28 is controlled to drive the external tooth ring 29 to rotate, and then under the connection of the connecting sleeve, the rotating shaft is driven to rotate, thereby driving the frustum-shaped grinding disc 12 to perform rotational operation; A set of seat I 32 is installed on the rotating shaft outside the grinding tank 10, and the seat I 32 is used to position the rotating shaft and the corresponding components at the bottom; It should be noted that for the positioning and support of structures such as the external gear ring 29, L-shaped fixing rod 31, internal gear 28, etc., during actual installation design, referring to the conventional structure is sufficient, and no further elaboration will be provided here.

[0030] As a preferred embodiment of the present invention, referring to Figure 2 , Figure 4 , Figures 9-10 , the power transmission unit includes a helical gear IV 38 connected to the end of the transmission belt 39 away from the main shaft 26 through a shaft rod. One side of the helical gear IV 38 is vertically engaged with a helical gear III 37. The side of the helical gear III 37 facing the inside of the grinding tank 10 is connected to a helical gear II 36 through a transmission shaft. The side of the helical gear II 36 facing the grinding ring 33 is vertically engaged with a helical gear I 35. The side of the helical gear I 35 facing the center of the grinding ring 33 is connected to a transmission rod. The end of the transmission rod is connected to a connection disk through a length adjustment member. The outer circumference of the connection disk is fixedly connected to the inner wall of the grinding ring 33 through a plurality of evenly distributed ring connecting rods 34. That is, under the transmission of the helical gear IV 38, helical gear III 37, helical gear II 36, helical gear I 35, etc., the grinding ring 33 is driven to rotate. When it is in contact with the inclined surface of the frustum-shaped grinding disk 12, the plant active raw materials on it are rotationally ground; Specifically, a set of seat II 40 is arranged on the transmission shaft, and the seat II 40 is used to maintain the support and positioning of the transmission shaft; Among them, the length adjustment member is set as an electric telescopic rod, and the electric telescopic rod is used to adjust the distance between the grinding ring 33 and the inclined surface of the frustum-shaped grinding disk 12, that is, to adjust the degree of grinding of the plant active raw materials; The angle adjustment unit includes a driven spur gear 43 sleeved on the transmission shaft. Gear sleeves 44 sleeved on the transmission shaft are installed and extended at both ends of the driven spur gear 43. One side of the gear sleeve 44 facing the grinding ring 33 is connected with a U-shaped connecting frame 45. One side of the U-shaped connecting frame 45 is connected with an L-shaped connecting rod 46. The end of the L-shaped connecting rod 46 is connected with a swinging base 47 sleeved on the transmission rod. The swinging base 47 is placed at the position between the length adjustment member and the helical gear I 35. A set of main spur gears 42 are meshed on the side of the driven spur gear 43 away from the L-shaped connecting rod 46. One side of the main spur gear 42 is connected with an auxiliary servo motor 41. The auxiliary servo motor 41 is fixed on the shaft seat II 40. When the auxiliary servo motor 41 is started to drive the main spur gear 42 to rotate, the driven spur gear 43 is then driven to rotate. Then, under the connection of the U-shaped connecting frame 45 and the L-shaped connecting rod 46, the swinging base 47 is controlled to drive structures such as the transmission rod and the helical gear I 35 to swing, thereby adjusting the contact position of the grinding ring 33 relative to the inclined surface of the frustum-shaped grinding disc 12, that is, performing position adjustment along the length direction of the inclined surface of the frustum-shaped grinding disc 12, so as to realize the step-by-step grinding of the plant active raw materials at each position on the inclined surface of the frustum-shaped grinding disc 12; It should be noted here that when the helical gear I 35 swings, it does not affect its meshing transmission with the helical gear II 36.

[0031] As a preferred embodiment of the present invention, the materials of the frustum-shaped grinding disc 12 and the grinding ring 33 are made of high-hardness wear-resistant materials, which are suitable for high-fiber and high-hardness plant raw materials, such as zirconia ceramics, tungsten carbide, and silicon nitride; Zirconia ceramics: Ultra-high hardness (Mohs hardness 8.5 - 9), excellent wear resistance, suitable for long-term grinding of fibrous raw materials (such as bark, rhizomes); Tungsten carbide: Hardness close to diamond (Mohs hardness 9 - 9.5), wear resistance far exceeding that of stainless steel, long service life; Silicon nitride: High hardness, high temperature resistance, low friction coefficient, suitable for high-speed grinding, good thermal shock resistance, suitable for cryogenic grinding, etc.; The specific selection is determined according to the type of the actually ground plant active ingredient raw materials, and details are not elaborated here.

The electrical connection is completed in the order of the working sequence of each electrical part. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the electrical control will not be described. (1) Raw material input and diffusion: The plant raw materials fall to the top of the frustum-shaped grinding disc 12 through the funnel-shaped feeding channel and are evenly diffused along the inclined surface; (2) Rotary milling: The main drive servo motor 17 drives the swing type rotary assembly through the multi-axis output assembly, driving the conical milling disc 12 to rotate. At the same time, the milling ring 33 rotates in the opposite direction under the drive of the adjustable rotary assembly, applying a shearing force to the raw materials. (3) Gradual filtration: When the raw materials slide down the inclined surface of the milling disc 33, they pass through the gradual filter holes of the elastic dividing ring 13 in sequence (for example: the aperture changes from 5 mm to 0.2 mm). The large particles are crushed by the extrusion of the milling ring 33, and the particles meeting the particle size requirements enter the next stage through the filter holes 14. (4) Dynamic adjustment: The auxiliary servo motor adjusts the contact angle between the milling ring 33 and the milling disc 12 through the gear set to adapt to raw materials with different fiber contents. (5) Screening and collection: The milled fine powder falls into the storage and transfer bin 16 through the screening trough. The unqualified particles are recycled to the milling area for continuous processing. The whole process requires no manual intervention, realizing automated continuous production.
